Running with collections of information is a cardinal facet of programming. Successful C, the IEnumerable<T> interface offers a standardized manner to work together with sequences of information. Frequently, you mightiness demand to dainty a azygous point arsenic a postulation, peculiarly once running with strategies that anticipate an IEnumerable<T>. This pattern simplifies codification and avoids penning particular instances for azygous objects. This article explores businesslike and idiomatic methods to walk a azygous point arsenic an IEnumerable<T> successful C, analyzing the advantages, possible pitfalls, and champion practices for seamless integration into your tasks.
Yielding a Azygous Point
The output instrument message provides an elegant resolution for creating an IEnumerable<T> from a azygous point. This attack avoids creating a fresh postulation successful representation, making it extremely businesslike. The output key phrase is a almighty characteristic successful C that permits you to make iterators connected-the-alert.
For case, see a script wherever you demand to walk a azygous drawstring to a technique that expects a postulation of strings:
national static IEnumerable<drawstring> SingleStringAsEnumerable(drawstring str) { output instrument str; }
This methodology generates an IEnumerable<drawstring> containing lone the enter drawstring with out allocating other representation for a fresh database oregon array. This attack is peculiarly generous once dealing with ample objects oregon once representation optimization is important.
Utilizing Enumerable.Repetition
The Enumerable.Repetition methodology supplies different handy manner to make an IEnumerable<T> from a azygous point. This technique generates a series that comprises the specified point repeated a fixed figure of instances. Successful our lawsuit, we repetition it erstwhile.
Present’s however you tin usage it:
utilizing Scheme.Linq; drawstring singleItem = "illustration"; IEnumerable<drawstring> enumerable = Enumerable.Repetition(singleItem, 1);
This snippet creates an IEnumerable<drawstring> containing lone “illustration”. Piece this methodology is easy, it’s worthy noting that it’s somewhat little businesslike than the output instrument technique, particularly for worth varieties, arsenic it entails creating a fresh enumerable entity. Nevertheless, the show quality is normally negligible for about applicable situations.
Creating a Azygous-Component Array
A elemental attack to make an IEnumerable<T> from a azygous point is to make a azygous-component array. Arrays implicitly instrumentality IEnumerable<T>, making them straight usable successful strategies anticipating this interface.
drawstring singleItem = "illustration"; IEnumerable<drawstring> enumerable = fresh drawstring[] { singleItem };
This technique is easy and easy comprehensible. Nevertheless, it includes allocating representation for a fresh array, which tin beryllium little businesslike than output instrument, peculiarly once dealing with ample oregon analyzable objects.
Leveraging Database.Adhd
You tin besides usage a Database<T> to accomplish the desired result. Piece this technique entails creating a database entity, it is inactive a viable action, particularly once dealing with mutable collections.
utilizing Scheme.Collections.Generic; drawstring singleItem = "illustration"; Database<drawstring> database = fresh Database<drawstring>(); database.Adhd(singleItem); IEnumerable<drawstring> enumerable = database;
This creates a fresh database and provides the azygous point to it. The Database<T> past implicitly implements the IEnumerable<T> interface. Akin to creating an array, this methodology includes allocation overhead however presents flexibility once additional manipulations of the postulation are required.
Selecting the Correct Attack: The output instrument methodology is mostly the about businesslike prime once you lone demand to dainty a azygous point arsenic an IEnumerable<T>. For eventualities involving mutable collections oregon wherever further operations mightiness beryllium wanted, utilizing a Database<T> oregon an array mightiness beryllium much appropriate. Enumerable.Repetition presents a concise syntax however tin beryllium somewhat little performant.

Question & Answer :
Is location a communal manner to walk a azygous point of kind T to a technique which expects an IEnumerable<T> parameter? Communication is C#, model interpretation 2.zero.
Presently I americium utilizing a helper technique (it’s .Nett 2.zero, truthful I person a entire clump of casting/projecting helper strategies akin to LINQ), however this conscionable appears foolish:
national static people IEnumerableExt { // utilization: IEnumerableExt.FromSingleItem(someObject); national static IEnumerable<T> FromSingleItem<T>(T point) { output instrument point; } }
Another manner would of class beryllium to make and populate a Database<T> oregon an Array and walk it alternatively of IEnumerable<T>.
[Edit] Arsenic an delay methodology it mightiness beryllium named:
national static people IEnumerableExt { // utilization: someObject.SingleItemAsEnumerable(); national static IEnumerable<T> SingleItemAsEnumerable<T>(this T point) { output instrument point; } }
Americium I lacking thing present?
[Edit2] We recovered someObject.Output() (arsenic @Peter urged successful the feedback beneath) to beryllium the champion sanction for this delay technique, chiefly for brevity, truthful present it is on with the XML remark if anybody desires to catch it:
national static people IEnumerableExt { /// <abstract> /// Wraps this entity case into an IEnumerable<T> /// consisting of a azygous point. /// </abstract> /// <typeparam sanction="T"> Kind of the entity. </typeparam> /// <param sanction="point"> The case that volition beryllium wrapped. </param> /// <returns> An IEnumerable<T> consisting of a azygous point. </returns> national static IEnumerable<T> Output<T>(this T point) { output instrument point; } }
Fine, if the technique expects an IEnumerable you’ve obtained to walk thing that is a database, equal if it accommodates 1 component lone.
passing
fresh[] { point }
arsenic the statement ought to beryllium adequate I deliberation
